1. What is UNS N08811?

UNS N08811is a nickel-iron-chromium alloy with approximately 30-35% nickel, 19-23% chromium, and balance iron, with controlled carbon, aluminum, and titanium for enhanced creep and rupture strength at high temperatures. This makes UNS N08811 material ideal for applications requiring long-term stability under stress, such as furnace tubes, heat exchangers, and superheater tubing. Compared to UNS N08810, UNS N08811 offers better creep resistance due to tighter carbon control and grain size.

Gangsteel’s UNS N08811 alloy steel plate is tailored for high-temperature industrial applications, providing a robust alternative to nickel alloy steel grades like UNS N08028 and UNS N08031.
